The Japanese ninjas who thrived during the Warring States and Edo periods were forced to disband due to their defeat, seemingly disappearing from history. However, in reality, up to 200,000 ninjas still exist in secret, covertly monitoring the world. The unremarkable Kuroi Unin (voiced by Sakai Taito) spends his days lethargically at home, appearing to be a complete loser, but he is actually a skilled ninja. One day, a superior disguised as a delivery person comes knocking, sending him to a certain high school to battle his arch-nemesis's ninja team. Kuroi, who has been dormant for too long, is finally called back by the organization, but this mission is not an ending; rather, it marks the beginning of a series of major events...This film is adapted from the manga of the same name by Kengo Hanazawa.
